David Liu has a new big idea: proteome editing. It could one day shred tau, RAS and some of the worst disease-causing proteins

Jason Mast

Editor

Before David Liu became famous for inventing new forms of gene editing, he was known around academia in part for a more obscure innovation: a Rube Goldberg-esque system that uses bacteria-infecting viruses to take one protein and turn it into another.

Since 2011, Liu’s lab has used the system, called PACE, to dream up fantastical new proteins: DNA base editors far more powerful than the original; more versatile forms of the gene editor Cas9; insecticides that kill insecticide-resistant bugs; enzymes that slide synthetic amino acids into living organisms. But they struggled throughout to master one of the most common and powerful proteins in the biological world: proteases, a set of Swiss army knife enzymes that cut, cleave or shred other proteins in everything from viruses to humans.

The Price of Relief: Exploring Solutions to the Rising Costs of Oncology Drugs

Checkpoint Therapeutics

In 2020, The National Cancer Institute estimated about 1.8 million new cases of cancer diagnosed in the United States, while the costs associated with treatment therapies continued to escalate. Given the current legislative climate on drug pricing, it’s never been more important to look at the evolution of drug pricing globally and control concerns of sustainable and affordable treatments in oncology.

How a tiny Swiss lab and two old blood samples created one of the only effective drugs against Omicron (and why we have so little of it)

Jason Mast

Editor

Exactly a decade before a novel coronavirus broke out in Wuhan, Davide Corti — a newly-minted immunologist with frameless glasses and a quick laugh — walked into a cramped lab on the top floor of an office building two hours outside Zurich. He had only enough money for two technicians and the ceiling was so low in parts that short stature was a job requirement, but Corti believed it’d be enough to test an idea he thought could change medicine.

A $3B+ peak sales win? Pfizer thinks so, as FDA offers a tardy green light to its JAK1 drug abrocitinib

John Carroll

Editor & Founder

Back in the fall of 2020, newly crowned Pfizer chief Albert Bourla confidently put their JAK1 inhibitor abrocitinib at the top of the list of blockbuster drugs in the late-stage pipeline with a $3 billion-plus peak sales estimate.

Since then it’s been subjected to serious criticism for the safety warnings associated with the class, held back by a cautious FDA and questioned when researchers rolled out a top-line boast that their heavyweight contender had beaten the champ in the field of atopic dermatitis — Dupixent — in a head-to-head study.

Rob Califf advances as Biden's FDA nominee, with a close committee vote

Zachary Brennan

Senior Editor

Rob Califf’s second confirmation process as FDA commissioner is already much more difficult than his near unanimous confirmation under the Obama administration.

The Senate Health Committee on Thursday voted 13-8 in favor of advancing Califf’s nomination to a full Senate vote. Several Democrats voted against Califf, including Sen. Bernie Sanders and Sen. Maggie Hassan. Several other Democrats who aren’t on the committee, like West Virginia’s Joe Manchin and Ed Markey of Massachusetts, also said Thursday that they would not vote for Califf. Markey, Hassan and Manchin all previously expressed reservations about the prospect of Janet Woodcock as an FDA commissioner nominee too.

Biogen vows to fight CMS' draft coverage decision for Aduhelm before April finalization

Zachary Brennan

Senior Editor

Biogen executives made clear in an investor call Thursday they are not preparing to run a new CMS-approved clinical trial for their controversial Alzheimer’s drug anytime soon.

As requested in a draft national coverage decision from CMS earlier this week, Biogen and other anti-amyloid drugs will need to show “a meaningful improvement in health outcomes” for Alzheimer’s patients in a randomized, placebo-controlled trial to get paid for their drugs, rather than just the reduction in amyloid plaques that won Aduhelm its accelerated approval in June.

CRO owner pleads guilty to obstructing FDA investigation into falsified clinical trial data

Zachary Brennan

Senior Editor

The co-owner of a Florida-based clinical research site pleaded guilty to lying to an FDA investigator during a 2017 inspection, revealing that she falsely portrayed part of a GlaxoSmithKline pediatric asthma study as legitimate, when in fact she knew that certain data had been falsified, the Department of Justice said Wednesday.

Three other employees — Yvelice Villaman Bencosme, Lisett Raventos and Maytee Lledo — previously pleaded guilty and were sentenced in connection with falsifying data associated with the trial at the CRO Unlimited Medical Research.

Cancer powerhouse AstraZeneca rolls the dice on a $75M cash bet on a buzzy upstart in the oncology field

John Carroll

Editor & Founder

After establishing itself in the front ranks of cancer drug developers and marketers, AstraZeneca is putting its scientific shoulder — and a significant amount of cash — behind the wheel of a brash new upstart in the biotech world.

The pharma giant trumpeted news this morning that it is handing over $75 million upfront to ally itself with Scorpion Therapeutics, one of those biotechs that was newly birthed by some top scientific, venture and executive talent and bequeathed with a fortune by way of a bankroll to advance an only hazily explained drug platform. And they are still very much in the discovery and preclinical phase.

‘Skinny labels’ on generics can save patients money, research shows, but recent court decisions cloud future

Zachary Brennan

Senior Editor

New research shows how generic drug companies can successfully market a limited number of approved indications for a brand name drug, prior to coming to market for all of the indications. But several recent court decisions have created a layer of uncertainty around these so-called “skinny” labels.

While courts have generally allowed generic manufacturers to use their statutorily permitted skinny-label approvals, last summer, a federal circuit court found that Teva Pharmaceuticals was liable for inducing prescribers and patients to infringe GlaxoSmithKline’s patents through advertising and marketing practices that suggested Teva’s generic, with its skinny label, could be employed for the patented uses.
